Parameters The operational characteristics of the POSITIP 850 can be modified via user parameters and operating parameters. While user parameters can be changed by the operator, operating parameters are given a fixed setting which corresponds to the details of the specific machine tool. The parameters are given a standard presetting in the factory.

P!?

All parameters are in non-volatile storage (i.e., they are not affected by power interruptions). All changes are effective immediately!

There are three groups of operating parameters: b P 1 .I to PI 3.0 - configuration of the user parameters b P21 .I to P28.0 - presetting of the user parameters b P40.1 to P99.0 - operating parameters for machine interface

These settings are normally made only once during commis sioning and then remain fixed.

Operating parameters can only be selected through code number 95148 and should not be changed by the machine operator. We recommend that you keep a written copy of the entry values for the operating parameters or store them on an external data medium.

Special Case: Mode of Operation and Working Plane

With this parameter you can select radius or diameter display for linear axes. If you select diameter, the symbol “0” will appear behind the display value. .

The drsplay for a rotary axis can be switched between degrees decimal and degrees/minutes/seconds.

With the scaling factor you can enter a correction to the workpiece to be machined. The correction range is (0.100000 to 9.999999). A scaling factor greater than 1 will enlarge the workpiece, while a scaling factor less than 1 will reduce it. You can enter a separate scaling factor for each axis.

By entering scaling factor OFF, all scaling factors are deactivated. When scaling factor ON is entered, the symbol “!” appears behind the drsplay value.

In the Probe Edge function the position value must be cor- rected by the radius of the ball tip. The entry range for the ball tip diameter of the edge finder is 0 to 199.999 mm.

The tool diameter can be entered in the user parameters and in the operating mode PROGO (single block, automatic and teach-in). The tool diameter value last entered becomes effec- tive automatically whenever radius compensation is entered.

With this parameter you can set the data transfer rate (baud rate) for the data interface.

With this parameter you can set the number of additional line feeds (blank lines) between values for an external device (maximum of 99 line feeds).

These parameters are not configured as user parameters in the factory presetting. With the Mode of Operation parameter you can choose among the BASIC, EXPERT and PROGO modes of operation vra the MOD key without switching the unit off. With the Working Plane parameter, the working plane can be selected during machining via the MOD key.

The user parameters Mode of Operation and Working Plane are only active if operating parameters P 9.0 and P 13.0 are configured as user parameters (see section 2.2).

P 40.” Counting Direction

P 41.” Signal Period

In the following description, axis-specific parameters are indicated by a parameter number with decimal point and asterisk (example: P I.“).

The asterisk signifies the axis-specific designation after the decimal point (e.g. P 1 .I, P 1.2 etc.).

Parameters which are not axis-specific are indicated by a 0 behind the decimal point (e.g. P 5.0).

The “User Parameters” menu is configured by enterrng posi- tions in operating parameters P I.* to P 13.0. The user para- meters can be configured in any desired sequence wrthin the positions 1-14. Position: 0 locks the respective parameter from access via the MOD key (see section 2.2).

These parameters are configured as user parameters in the factory presetting (see sections 2.2 and 4.1).

With parameters P 1.” to P 8.0 as user parameters, all 14 freely selectable field positions are occupied. If you wish to define parameters P 9.0 and P 13.0 as user parameters, you must overwrite already occupied user parameters (e.g. parameter 8.0 Line Feed).

User parameters can also be set in the operating parameters (P 21 .I to P 28.0). making it possible to change even locked user parameters. Changing these parameters is effective regardless of whether they are changed in the “User Parame- ters” or in the “Operating Parameters” menu. (For description, see section 4.1.)

With parameter P 40.” you can set the counting direction sep- arately for each axis.

The signal period of the connected linear encoders is entered in parameter P 41.“. If linear axis movement is measured using rotary encoders with nut and spindle, the signal period must be calculated with the following formula:

Signal Period ,pml = Spindle Pitch [mm1 ~1000 Line Count

Line count (P 42.“) and angle subdivision (P 44.“) are neces- sary only for rotary axes. For linear axes whose traverse is measured via rotary encoders with nut and spindle, the axis must be defined as a linear axis in parameter P 48.“.

41

P 42.” Line Count

The line counts of rotary encoders connected to rotary axes must be entered in parameter P 42.“.

P 43.” Linear Subdivision

P 44.” Angle Subdivision

The subdivision factor is entered in parameter P 43.“. The sub- division factor determines the display step and depends on the setting of the signal period (see Table 3.1).

The angle subdivision determines the display step for rotary axes and depends on the line count setting (see Table 3.2).

P 45.” Distance Coding

Parameter P 45.” defines whether the display unit is to evalu- ate signals from encoders with single or with distance-coded reference marks. For encoders with single reference marks, enter none in parameter P 45.“. For distance-coded reference marks, the entry value depends on the encoder model (see Table 3.3).

P 46.” Monitoring

With parameter P 46.” on, the corresponding encoder input signal is checked for the following errors: 0 excessive traversing speed l cable break l measuring signal error These errors are then displayed on the screen.

P 47.” Machine error can be measured with the aid of a comparator Linear Correction measuring system (e.g. VM 101 from HEIDENHAIN). These

errors can be entered in parameter P 47.” as a linear correc- tion factor in parts per million (ppm) measuring length.

Example: Measuring length 620 mm Value actually measured (e.g. via VM 101) 619.876 mm Difference =- 124um

Conversion to 1 m measuring length - 124 urn. 1000 mm

Display of the bolt hole circle graphics can be set in parameter P 54.0 in the case that it deviates from the normal coordinate system. Off: no mirroring ver: the vertical coordinate axis is mirrored hor: the horizontal coordinate axis is mirrored ve + ho: both coordinate axes are mirrored

When an axis is mirrored, the direction of rotation for hole numbering is changed in the graphics.

Depending on the setting of parameter P 54.0, parameter P 55.0 defines the direction of rotation of the holes in the bolt hole circle graphics. normal: direction of rotation (in the graphics) is from the first

to the second axis. inverted: direction of rotation (in the graphics) is from the

second to the first axis.

Parameter P 56.” defines a range around “zero” in which a zero crossover signal will be generated (see External Functions). Input range: 0 to 99.999 mm.

The current measured value is stored and output over the RS-232-C data interface with every storage procedure (CTRL, pulse, contact). The display on the screen can be set with parameter P 57.0: Off: the display is not stopped during a storage

signal concrnt: the display is stopped only for the duration of the

storage signal stopped: the display is stopped, but is updated by every

storage signal

In the distance-to-go function, the actual value can be dis- played instead of the graphic positioning aid. bar: graphic positioning aid actual value: display of the absolute position in small type

beneath the distance-to-go display.

Parameter P 59.0 allows input of a delay time (in minutes) for protective standby mode. If no keys are pressed and no axis movements take place for the length of time entered as the delay time, the screen image is reversed. This prevents screen burning. 5 - 98: delay time in minutes

99: no protective standby mode.

P 61.0 Probe/%-232-C

With parameter P 61.0 set to on, after probing with the edge finder [edge, centerline, or circle center) a storage signal is generated and the measured value is sent over the TXD output of the FE-232-C data interface. If no external device (such as a printer) is connected, parameter P 61.0 must be set to off. Otherwise the error message EXTERNAL UNIT NOT READY will appear after every probe.

P 99.0 Counter Application

With parameter P 99.0 the POSITIP 850 is set up either for milling or turning.

Data Interface

1 Definition of the RS-232-WV.24 Interface

POSITIP is equipped with a data interface according to EIA standard RS-232-C (CCITT standard V.24).

The data transfer code is ASCII with even parity bit. The K-232-C data interface is designed for serial data transfer; devices with parallel data interfaces cannot be connected. Levels for TXD and RXD (negative level for “1”):

4 Data Transfer Measured values, part programs and operating parameters can transferred over the PT 850’s RS-232-C data interface. The data interface can operate with t.wo different data transfer protocols: b External data transfer protocol (EXT) for printers, punching

units, readers and other peripherals. b FE data transfer protocol (FE) for the HEIDENHAIN FE 401

Floppy Disk Unit or a suitably adapted computer.

baud rate in order to avoid errors in data transfer. The desired baud rate is selectable under the user parameters (via the MOD key). The selected baud rate must be identical to the baud rate of the peripheral device.

In FE mode (for the FE 401 Floppy Disk Unit from HEIDEN- HAIN), the data transfer rate is always 9600 baud regardless of the baud rate set via the MOD kev.

4.3 Measured Value Output

The current display value can be transferred over the E-232-C data interface to peripheral equipment such as a printer. After a storage command, the measured value is out- put (for a maximum of 4 axes) through an internal buffer. The storage signal can be generated via the RS-232-C interface, the “external functions”, or via probing with the edge finder.

4.3.1 Storage via RS-232-C Interface

When the control character CTRL B (= STX) is transmitted, a storage signal is generated and the measured value is trans- mitted over the TXD output of the RS-232-C data interface. The duration of data transfer depends on the selected baud rate. the number of axes and the number of line feeds.

In the PROGO mode of operation, It IS possible to read pro- grams into or out of POSITIP over the RS-232-C data interface (see Working with the POSITIP 850).

Operating parameters can be input and output over the RS-232-C data Interface. Printers connected to the PT 850 must be equipped with a serial RS-232-C interface (for the data format see section 4.2).

Programs and operating parameters with the same program number can be stored with the FE 401 Floppy Disk Unit from HEIDENHAIN. When loading operating parameters, POSITIP automatically generates program number 850 unless a differ- ent number is entered.
